OLE ANDREW NESS, OF ZUMBROTA, MINNESOTA.

AIR-BRAKE COUPLING.

SPECIFICATION forming part of Letters Patent No. 682,882, dated September 1'7, 1901.

Application filed January 11, 1901. fierial No. 42,907. (No model.)

To aZZ whom it may concern:

Be it known that I, OLE ANDREW N ESS, a citizen of the United States, residing at Z umbrota, in the countyof Goodhue and State of Minnesota, have invented new and useful Improvements in Air-Brake Couplings, of which Y the following is a specification.

My invention relates to air-brake couplings; and the object of the same is to produce a de- IO vice of this character which will be simple in be coupled by hand.

With this endin view I have designed the simple and novel construction which is fully described in this specification and claimed, and illustrated in the accompanying drawings, forming a part thereof, in which- Figure 1 is a side elevation of my complete device attached to two cars, which are shown in fragment. Fig. 2 is a longitudinal section of one member of the coupling. Fig. 3 is a front elevation of the same. Fig. 4 isa transverse vertical section on the line a: m, Fig. 1. Like numerals of reference designate like parts in the different views of the drawings. The two members of my coupling are coun- Therefore the detailed description will be confined'to one.

The numeral 1 design ates cars each equipped with a member 2 of my coupling. These cars have an ordinary form of coupling 3, which 3 5 provides supporting means for the members- 2,-which are connected thereto by a hangerarm 4. The arm 4 is bent over at 4 to engage the couplingfi and extends down and is rigidly attached to a frame or sleeve 5, which supports the members 2. Each member of the coupler consists of an apertured head 6, fitted on the endof a shank 7, comprising a large cylinder 7 and a smaller squared portion 7, both traversed bya bore 8, which establishes communication between the head and a hose-pipe 9. The aperture 10 in the sleeve 5 is made of two sections 10 and 10? to correspond with the contour of the shank 7, thereby leaving it free to slide until shoul- A valve 13, which has a handle 14, is seated in the rear of the shank 7 and is connected by a rod 15 with the sleeve 5. By this arrangement the valve is tion is made between the heads 6 by means ofa conical projection 17 on each of the heads, which fits a conical recess 18 on the opposite head, and rubber gaskets 19, seated in the outer faces and surrounding the mouths 0fthe bores 8. The conical projections 17, in

combination with the corresponding recesses, formguides, and thus permit the coupling to bemade by bumping the cars together.

In order to make the mounting of the coup ler more secure, and thereby obviate the dan= ger of the breaking of the arm 4, truss-braces 20 are provided, which braces are connected to the coupling 3'at 21 and to the sleeve 5 by means of a stud 23, engaging a slot 24. Arms 25 are secured one to each side of the sleeve by pins 28', are bent at right angles at 26, and embrace the end 27 of the brace. Pins 28 are footed in the side of the sleeve 5 and project through the arms 25and spiral springs-29,surrounding them, which springs bear against nuts 30 at one end and against the arms 25 at the other. By this combination latitude is given for a sidewise movement of the heads 6 in rounding a curve. 7

The act of uniting the two members 2 together is performed simultaneously with the coupling of the cars, which action will cause theheads 6 to contact and the cones to enterthe recesses, the springs to retract until the shoulders 11 and 12 abut, and the valve 13 to be opened through the agency of the rod 15.

I do not wish to be limited as to details of construction, as these may be modified in many particulars without departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and wish to secure by Letters Patent, is-

In a coupling member, the combination, of a sleeve rigidly supported, a longitudinallyapertured shank slidingly mounted in said sleeve, stops to limit the rearward movement of said shank, an apertured head formed integral with said shank, a spring surrounding seated in said head and surrounding the outer IO end of the said aperture therein.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

OLE ANDREW NESS.
